The interfering part is preferably constituted by an arm 25, which ispivoted on a screw 26 fixed in a lug 27 on the rear end of thefiring-pin chamber 7. One end 28 of this arm is normally caught behind ashoulder or head 29 on the rear end of the firingpin, which is adaptedto project outward through a hole 30 in the back end of the firing-pinchamber. The portion 31 of the arm at the other side of the pivot 26projects for a suitable distance and is formed with a longitudinal slot32.

The swivel 6 constitutes a form of adjust ment enabling the device to beset into interfering position or to be moved out of such position. Inconnection with an adjustment of this character a safety means isprovided for positively locking the device in position and also forlocking the firingpin in the non-interfering condition of the device. Asa further safety, a means is also provided whereby the release arm 25 isalso looked against releasing movement when the device is in thenon-interfering condition. In the illustration a split safety pin 33having a ring handle 3% is employed. In the interfering or operativecondition of the parts, this pin is inserted at the side of thefiring-pin chamber 7 of the swivel structure 6 into a socket 35 in thebase, thus preventing the structure being turned clockwise, in Figs. 2and 5, to the non-interfering or inactive position, displacement of thestructure in the opposite direction being prevented by a post 36 risingfrom the base at the opposite side of the structure or by any othersuitable fixed stop. In the non-interfering position of Figs. 1 and 10,the safety-pin is inserted through holes 37 in the tiring-pin chamberdirectly in front of the firing-pin down ward into another socket 38 inthe base. In this manner both the adjustment and the firing-pin arelocked. In order automatically to lock the release-arm 25 when thedevice is turned to the non-interfering position, the post 36 is formedwith shoulders or a recess 39, in or adjacent which the projecting partof the arm lies in this position, so that it cannot be turned upon itspivot so as to release the firing-pin. In this position, therefore, thesafety-pin 33 serves both to lock the adjustment in the non-interferingposition and to prevent the releasearm 25 being accidentally displacedfrom the restraint of the lock 39.

In the case of a door. the base is secured by screws 40 passing throughthe screw-hole sockets 2 to the vertical face of a door-jamb 41 adjacentthe free edge of the door 42 and inside the apartment. As thuspositioned, the projecting portion of the arm 25 overlies the inner faceof the inwardly opening particular substance.

door when the device is set in protecting position. Consequently if thedoor is opened, the yielding interference afforded by the arm will causethe arm to turn upon its pivot thereby disengaging its end 28 from theshoulder of the firing-pin, which is thereupon driven forward by thespring 18 against the cartridge, which is exploded, thereby giving thealarm. During the daytime, or when the protection is not desired, thedevice is shifted to the position of Fig. l, in which position tlzeinterference is removed from the door. which can now be opened andclosed freely with out actuating the device.

In the case of a window, the base is attached to the top surface of thelower sash a3, in such position that when it in the interferingcondition of Fig. 4 the arm 25 overlaps one of the stiles of the uppersash 44; In this stile a suitable pin 45 is driven, so as to projectwithin the slot 32 of the arm. Ireferably there will be a series ofthese pins 45 at difi'erent heights, so that the window can be protectedin any one of a number of open positions as Well as when fully closed.In the non-interfering position the arm 25 is carried clear of the uppersash, as seen in Fi 3.

Fig. 12 illustrates the combination of the alarm device with a fume orgas producer a6, adapted to repulse or incapacitate the intruder. Thismeans may be considerably varied and may be either mounted upon thesupport alongside the alarm or incorporated upon the same base. A simpleconstruction is shown, comprising a cup d7 containing a body offume-producing material 48 and having a flash-tube 49, which in theoperative condition is in line with and adjacent the cartridge-chamber 9and its cartridge 12, the flash-tube being so positioned as to conductthe flame from the exploded cartridge to the material 48, which isthereby ignited and caused to give off noxious fumes. Ti'ie material 48may be, for example, a cake of sulfur, but I do not limit myself to theAs indicated'at 50 a special ignition substance may be provided as asurface layer upon the cake or otherwise. A perforated cover 51 on thecup 47 may be provided to protect the contents and to guard againstpossible damage from escape of particles of the burning material.

The cup 47 is also connected with the base '52 by a swivel 53 similar tothe swivel of the alarm proper, enabling it to be turned into and out ofoperative position.

I recognize that the form and details of the invention may be varied,and therefore do not Wish to limit myself to the precise constructionwhich is herein illustrated as a preferred embodiment.

Fig. 14- illustrates a cartridge chamber member 9 the forward portion orbarrel 10 of which is of sufficiently narrow diameter and sufficientlylong to be reversed and inserted in the firing-pin chamber to press backthe firing-pin against the action of its spring, so that the firing-pinmay be caught again by the arm 25 after the device has been fired.

What I claim as new is:

l. A burglar-alarm device, comprising a base having means of attachmentto a surface at a door or Window, and a structure movable relatively tothe base, said structure including a cartridge-chamber andspringactuated firing-means and affording also a yielding interferenceto the opening of the door or Window whereby the firing-means isieleased, said structure being movable relatively to the base so as tobring the interference into and out of interfering position, and safetypin means for locking the structure in and out of interfering position,the safety pin in the non-interfering position also blocking thefiring-means.

2. In an alarm for a door or other closure, a base, a structure movablymounted on the base and including a firing-pin chamber and acartridge-chamber, a spring-actuated firing-pin in the firing-pinchamber, a release for the firing-pin affording a yielding interferenceto the opening of the closure, and a safety-pin structure insertable insaid movable structure and into the base to lock the structure innon-interfering position and at the same time block the firingpin.

3. In a cartridge-alarm for a door or other closure, a base, afiring-pin chamber sWiveled on the base, a spring-actuated firing-pintherein, a cartridge-chamber in line with the firing-pin chamber, and areleasearm pivotally connected With the sWiveled firing-pin chamber andadapted to offer interference to the opening of the closure and to bemoved into and out of interfering position by turning the swivel.
